Endophytic fungi are described as symbionts that enhance plant resilience to abiotic stress through physiological, biochemical, and molecular pathways. The review frames them as hidden regulators of plant stress resilience.

The review states that fungal lineages show different stress-mitigation strategies, with Ascomycota emphasizing metabolite production and hormonal control, Basidiomycota emphasizing root-fungus signalling and resource acquisition, and Zygomycota emphasizing nutrient mobilisation and rapid colonisation.
The review states that interactions with named endophytic fungi can allow plants to sustain photosynthesis, nutrient uptake, and growth under drought, salinity, heat, and heavy metal stress.
The review states that addressing current deployment challenges will require omics-driven innovations, efficient delivery methods, improved links between empirical research and on-farm application, and policy frameworks.
The review states that endophytic fungi mitigate plant abiotic stress through osmotic regulation, ion homeostasis, antioxidant defence, hormonal modulation, and epigenetic reprogramming.
The review states that key barriers to agricultural deployment include inconsistent field performance across host genotypes, overlap between beneficial and pathogenic traits, and limited inoculant mass production.
The review states that integrating fungal symbionts into climate-smart agriculture has potential to improve productivity, adaptation, and mitigation in stress-prone agroecosystems.
